That is not a policy choice that could be reversed later — it is how the site is built. There is no server to send anything to.
Nothing. There is no analytics script, no cookie banner because there are no cookies, no accounts, no logging of prompts, and no third-party trackers.
The models are downloaded once from Hugging Face’s CDN and then execute inside your browser, on your own processor. Your prompts are never transmitted — they are consumed in a Web Worker on your machine and discarded.
Conversations and your model choice are kept in this browser’s localStorage, and the model weights in its Cache Storage. Both are on your disk, readable only by this site, and never uploaded. Deleting a conversation removes it; clearing site data removes everything, including the cached models.
Two third parties see a plain file request, and nothing about you beyond the fact that a browser asked for a file: Hugging Face serves the model weights, and Vercel serves the page itself. Neither receives your prompts, because your prompts never leave the tab.
You do not have to take this on trust. The site is open source and the inference worker is a single readable file — read it.
